Frequently Asked Questions
What is a screw down check globe valve?
A screw down check globe valve combines the functions of a globe valve and a check valve. It allows fluid to flow in one direction while automatically preventing backflow, and the screw-down stem can be manually closed to completely stop flow for maintenance or emergencies.
What are the standard pressure ratings and sizes?
These valves are rated for 20 kgf/cm2 (about 284 psi) and are available in sizes from DN15 to DN150 (1/2" to 6"). Flanged connections are standardized to JIS, DIN, or ANSI requirements.
The valve body is made of cast steel (WCB) for strength and durability, while the internal trim (seat and disc) is typically stainless steel or bronze to resist corrosion in marine environments.
Are these valves suitable for seawater applications?
Yes, the cast steel body and corrosion-resistant trim make them suitable for seawater, as well as fuel oil, lubricating oil, and freshwater systems commonly found on ships.
